How to clear data from Table-Control

Former Member — Mon, 20 Nov 2006 04:46:55 GMT

Hi all,

I am working on table control. I have some data on the table control.

When I press the 'Cancel' button, I require that the table-control should be cleared.

I tried using REFRESH CONTROL TC01 USING SCREEN 1001. But, the data doesn't get cleared.

Please advise.

Regards,

Saurabh Buksh.

Hi ,

I think screen will not get refreshed once you clear the records in the table control .

try calling the same screen again after you clear the table Control .

Hi,

I want to ask, whether this will delete the data from the database table.

Actually I don't want to delete the data from the database table. I just want to clear my table control.

Thanks & Regards,

Saurabh Buksh.

good

try this example

REPORT demo_dynpro_tabcont_loop_at.

CONTROLS flights TYPE TABLEVIEW USING SCREEN 100.

DATA: cols LIKE LINE OF flights-cols,

lines TYPE i.

DATA: ok_code TYPE sy-ucomm,

save_ok TYPE sy-ucomm.

DATA: itab TYPE TABLE OF demo_conn.

TABLES demo_conn.

SELECT * FROM spfli INTO CORRESPONDING FIELDS OF TABLE itab.

LOOP AT flights-cols INTO cols WHERE index GT 2.

cols-screen-input = '0'.

MODIFY flights-cols FROM cols INDEX sy-tabix.

ENDLOOP.

CALL SCREEN 100.

MODULE status_0100 OUTPUT.

SET PF-STATUS 'SCREEN_100'.

DESCRIBE TABLE itab LINES lines.

flights-lines = lines.

ENDMODULE.

MODULE cancel INPUT.

LEAVE PROGRAM.

ENDMODULE.

MODULE read_table_control INPUT.

MODIFY itab FROM demo_conn INDEX flights-current_line.

ENDMODULE.

MODULE user_command_0100 INPUT.

save_ok = ok_code.

CLEAR ok_code.

CASE save_ok.

WHEN 'TOGGLE'.

LOOP AT flights-cols INTO cols WHERE index GT 2.

IF cols-screen-input = '0'.

cols-screen-input = '1'.

ELSEIF cols-screen-input = '1'.

cols-screen-input = '0'.

ENDIF.

MODIFY flights-cols FROM cols INDEX sy-tabix.

ENDLOOP.

WHEN 'SORT_UP'.

READ TABLE flights-cols INTO cols WITH KEY selected = 'X'.

IF sy-subrc = 0.

SORT itab STABLE BY (cols-screen-name+10) ASCENDING.

cols-selected = ' '.

MODIFY flights-cols FROM cols INDEX sy-tabix.

ENDIF.

WHEN 'SORT_DOWN'.

READ TABLE flights-cols INTO cols WITH KEY selected = 'X'.

IF sy-subrc = 0.

SORT itab STABLE BY (cols-screen-name+10) DESCENDING.

cols-selected = ' '.

MODIFY flights-cols FROM cols INDEX sy-tabix.

ENDIF.

WHEN 'DELETE'.

READ TABLE flights-cols INTO cols

WITH KEY screen-input = '1'.

IF sy-subrc = 0.

LOOP AT itab INTO demo_conn WHERE mark = 'X'.

DELETE itab.

ENDLOOP.

ENDIF.

ENDCASE.

ENDMODULE.
